Coming off the ridiculous number of injuries last year, it would have been pretty hard to have a gameplan for this season. Who could you be absolutely certain was going to be a contributor? Barring blowing up the whole team that is, but there was too much "potential" in too many players for that to be realistic, either. It's been pretty lousy to be a fan for the last couple years, but at least this coming offseason you can have a more legitimate evaluation of what you have in the players on the team from this year. That's what has me a little more optimistic. I don't expect grand things from the team next year, but they're showing the signs of having bottomed out and moving upwards again. The ceiling doesn't appear to be really high yet, but it's easier to identify what to work on.
The real question is what kind of team do you want? The Marlins have two fairly recent World Championships, followed up by dismantling the team and playing lousy baseball for years. And honestly, for some fans, that is what they want. Competing but ultimately failing doesn't leave a great feeling after it's all done (many of us also get the pleasure of being Vikings fans - Yay). Winning a championship so you have something to brag about is ultimately what you aspire to. But baseball is a different sport than the other big ones in that winning 60% of your games is ultimately regarded as being very successful, where the other sports the really good teams win more like 75-80%, some even more. It's pretty hard to build a team that you can say "that's definitely a championship team" in baseball, because a 10-win difference in record out of 162 games really isn't all that much (i.e equivalent to a 1-game difference in record in Football). We've been conditioned to believe a 95-win team is way better than an 85-win team, which is in turn way better than a 75-win team, but they're probably not much, ultimately.
The season is 162 games long over the course of 6 months. Teams are going to change over the course of that time. The current team looks better than the team that started the season, but naysayers can (understandably) claim you can't just cherrypick when to start counting the record from. Last year's team had a silly-good month of being the best pitching team in baseball, which led to the mirage of being competitive, only to ultimately regress back. This year's uptick feels a little more legitimate to me, but not everyone will agree. I'm more inclined to believe Span, Revere, Mauer, Willingham, Doumit, and Morneau (and possibly Plouffe) will continue to hit well than I was to believe last year's team could keep pitching like they did for that short stretch. But it could come crashing down pretty fast, too, if the D's regress as a pitching staff (not hard to believe will happen) or if any of the hitters get hurt or cool off.
The Twins need better starting pitching, I doubt you'll find a single person to argue that. But look at last year's Phillies. In the discussion as the best starting rotation ever, first round flameout in the playoffs. How many championships did the Braves win in the 90's? There's no ultimate answer "do this and you'll win." The 2001 Seattle Mariners went 116-46, and didn't win the series. I see a Twins team with a fairly good looking lineup 1-7 when everyone is healthy, and some pretty suspect pitching. And most of the suggestions revolve around trying to keep that 1-7 in pretty good working order and somehow improving the pitching. There are some reasonable suggestions to do that (move Morneau or Span to get pitching, put Parmelee in the lineup), but they don't guarantee success. They just indicate a team is trying to do something. We've tried to do things in the past, some have worked (Shannon Stewart), some haven't (pick one, there's lots). After an offseason of doing very little and not getting much better recordwise, the temptation to recommend numerous ways to get better by trading/signing/firing/whatever is pretty understandable.
If you enjoy watching the Twins right now, good for you. If you believe this team needs serious work and the owners/front office/coaches/players need to be held to a higher standard, good for you. Passionate fans are better than apathetic fans. </soapbox>
